Learn the most important SQL skills and apply them in your job—quickly and efficiently!

SQL (Structured Query Language) is the modern language that almost every relational database system supports for adding data, retrieving data, and modifying data in a database. Although basic visual tools are available to help end-users input common commands, data scientists, business intelligence analysts, Cloud engineers, Machine Learning programmers, and other professionals routinely need to query a database using SQL.

Job Ready SQL provides readers with an understanding of relational databases and Structured Query Language (SQL). SQL is a domain‐specific language designed for managing data held in a relational database management system. This book contains a full‐fledged SQL course that is used by the Wiley Edge Global Academy and the Software Guild to train our alumni in SQL and other topics, such as data analysis and Data Science.

Job Ready SQL provides you with the foundational skills necessary to work with data of any kind. Offering a straightforward ‘learn-by-doing’ approach, this concise and highly practical guide teaches you all the basics of SQL so you can apply your knowledge in real-world environments immediately. Throughout the book, each lesson includes clear explanations of key concepts and hands-on exercises that mirror real-world SQL tasks.
